Creating awareness for the processes of permafrost thaw, is our motivation. We want to show what happens, when permafrost thaws - what it means to ecosystems and people living in the

Permafrost Modelling Profile Why do we need Permafrost Models? Permafrost models are important tools to investigate the role and the sensitivity of frozen ground under very complex environmental and climatic [...] Since permafrost is usually not visible at the earth’s surface and only few measurement sites exist, models are also important to investigate the current state of permafrost. Furthermore, permafrost models [...] the elements that we are able to simulate with our permafrost-land surface model. (Graphic: Alfred-Wegener-Institut) What are Permafrost Models? Permafrost models provide information on ground temperatures

Coastal Permafrost Profile About 34% of the world's coasts are affected by Arctic permafrost and are particularly sensitive to climate change. The frozen cliffs lose their cohesion, which is ensured by [...] ble to quantify the amount of eroded sediment and organic material more accurately. The group "Permafrost Coasts" investigates the velocity and character of sediment and organic matter transport into the [...] echosounder bathymetry: to quantify the content of particulate and dissolved organic material in permafrost sediments and their bottom ice and to characterize its spatial variability; to quantify the velocity
